How many squares of roofing and how many pieces of ridge shingles are needed for the roof in Figure 15.19? The slope of the roof is 4:12 and the exposure is 5 inches wide. From Problem 17, the area of the roof is 1,004 sf or 10.04 sq.
What will be an ideal response?
Starter course = 34? of eave per side × 2 sides × 5? / 12 in per ft = 28 sf = 0.28 squares
Squares of roofing = 10.04 squares + 0.28 squares = 10.32 squares
Ridge shingles = 34? × 12 in per ft / 5? per shingle = 82 pieces
